How to use FreezedUnionCase.snake for model class
I am using freezed package as a code generator. My response from API as shown below,
first_name,
last_name,
etc..,
And I am defining my model class like this,
firstName,
lastName,
etc..,
If I use @JsonKey(name: 'first_name')
then it works but I have to write this annotation for every field I have. Is there any way to set it global?

Can you make complete apps using Flutter & Dart or just the UI part of an app?
I'm confused about what Flutter framework actually does, I know that it uses Dart and have heard that both of them can be used to create cross-platform apps.
But Wikipedia defines Flutter as a "UI Framework", so my question is, can you make a complete app (for mobile) which also has backend part (communicates with a database) built entirely using Flutter & Dart and not only the UI part?
If you didn't get my question, here is an example:
Suppose a front-end web developer works on client side programming in his job, and the backend logic is written by another backend developer.
When it comes to mobile app development, suppose as a Flutter developer, your job is to create apps, but does that mean that as a Flutter developer, you'll only write the front-end logic and leave the backend part for another backend developer like in web world? Can Flutter developers also write the backend of an app using only Flutter & Dart? If not, then who writes the backend of a mobile app and what tools/languages/frameworks does he uses?

How to map nested freezed union classes to drift/moor sql tables?
I need to save this Objects into a SQL/Drift DB, how can/should I design die Tables/Rows for an efficient mapping?
Here is are examples of a (deep)nested union class. It itself is a union class and also has a field which in itself is also a union class again.
What is the best way to deal with this?
@freezed class TemplateDto with _$TemplateDto { const factory TemplateDto({ required String templateID, required String userID, required String organisationID, required bool shareWithOrg, required bool shareGlobal, required TemplateDataDto templateDataDto, }) = _TemplateDto; ... } @freezed class TemplateDataDto with _$TemplateDataDto { const TemplateDataDto._(); const factory TemplateDataDto.templatePack({ required String templateName, required List<String> templatesInPack, }) = TemplatePackDto; const factory TemplateDataDto.homeworkTemplate({ required String templateName, required HomeworkDataDto homeworkDataDto, }) = HomeworkTemplateDto; const factory TemplateDataDto.XXXX({ ... }) = XXXTemplateDto; ... } @freezed class HomeworkDataDto with _$HomeworkDataDto { const HomeworkDataDto._(); const factory HomeworkDataDto.oneTimeHomework({ required String homeworkName, required String homeworkDescription, required bool isActive, @JsonKey( includeIfNull: true, defaultValue: false, ) required bool isPartOfMultiHomework, required DateTime dueDate, }) = _OneTimeHomeworkDto; const factory HomeworkDataDto.multiOneTimeHomework({ ... }) = _MultiOneTimeHomeworkDto; const factory HomeworkDataDto.recurringHomework({ ... }) = _RecurringHomeworkDto; ... }

using json_serializable with json that have many dynamic keys
i have a json object that psossibly contains +200 keys , those keys can increase in the future
typing those in a class is hard even with code generation
in typescript i would just :
type IoData = { [key: string]: any; };
how can I handle this with json_serializable
example
